Abstract
A display apparatus, includes: a display light emission unit which includes a light source, forms an image, and emits display light corresponding to formed image; a deflection unit which deflects the display light; a narrow band reflection unit which has characteristics of reflecting only light in a reflected wavelength range and transmitting light of wavelengths other than the reflected wavelength range, and reflects the display light incident from the deflection unit towards a viewpoint; and a control unit which changes an incidence angle at which the display light is incident on the narrow band reflection unit, in accordance with change in a wavelength of the light, wherein the narrow band reflection unit is configured such that the reflected wavelength range changes when an incidence angle of light changes, and the control unit changes the incidence angle such that a wavelength of the light is included within the reflected wavelength range.
